Feature update, Admin impact


We will soon begin redirecting users from the legacy Office 365 Security and Compliance center ( to Microsoft 365 Defender portal (, for all security workflows including: Alerts, Threat Management and Reports.
Items in the Office 365 Security and Compliance center that are not related to security will not be redirected to Microsoft 365 Defender. For compliance solutions redirection to Microsoft 365 Compliance Center, see (March 2021, MC244886).
This is a continuation of our migration of the security workflows to the Microsoft 365 Defender portal, which we started in March 2021.
For customers who have already enabled automatic redirection, as part of the previous communication when announcing the New Home for Microsoft Defender for Office 365, automatic redirection will now include alerts and alert policies redirection, in addition to all previously redirected features. As before, customers will still be able to turn off automatic redirection.
Please refer to the redirection support documentation here for additional details.
